There are few better ways to celebrate Earth Day than supporting a good cause -- and hearing some great live music while you're at it. Anti-captivity activists will be coming out in droves to the "Kiss the Sky! Orca Freedom Concert" held in support of wild orca research in Seattle, WA.
The concert will be headlined by Heart, a longtime anti-captivity band and outspoken supporter of the documentary "Blackfish." Also there to perform will be Graham Nash and Jami Sieber, Joan Jett and the Blackhearts, Arielle, Country Joe McDonald and Andrew Morse.
